Explanations

A. A. C. D. E.

E&amp;M signaling is often the preferred option for CAS because it avoids glare, it provides answer/disconnect supervision and it can receive Automatic Number Identification (ANI) with FGD and send ANI with FGD-EANA.

In other words, you can have 1 channel-group for incoming calls and 1 channel-group for outgoing calls.
